Maersk says "No" to shipping imperiled species?

I have long believed that logic would prevail over greed. And that the people who have benefited from over-exploiting the sea would realize that they are shooting themselves in the foot. If you over-fish, the fish go away, and you are out of business. Duh. But, I get ahead of myself...
The news that such a large shipping company like Maersk would review its policies and possibly refuse to ship Chilean sea bass (Patagonian toothfish), Orange roughy, shark products (YEAH!), and any whale meat, is nothing short of spectacular. Although Greenpeace says they have new policy in place, other sources say the company is reveiwing its policies. There is no statement on the Maersk website.
Regardless, I feel the tide is slowly, slowly, turning. If the groundswell of grass-roots and sophisticated organizations can sway large companies, there is surely light at the end of the tunnel.
